  1. ZFS Server unerreichbar nach File Transfer

    Hallo, Mir ist heute aufgefallen, dass wenn man größere Dateien auf den FileServer (Win Server 2016 VM) überträgt, diese langsam beim Transfer beginnen und zum ende hin eine normale Geschwindigkeit erreichen. Blöderweise steigt der Server Load ebenfalls unproportional an (bis auf über 25, GUI...

  5. Proxmox ZFS UEFI Boot failure

    Hello all, Some weeks ago our Server didnt boot automatically anymore. We scheduled a reinstallation for next week, due the system was installed on UEFI what is not best practise. Since that Problem occurs, we were always able to boot the System via Proxmox Rescue Boot. Today the Server was...
  6. ZFS bad Performance!

    Thank you very much for your recommendation. I will have a look at it :)
  7. ZFS bad Performance!

    Thanks for your Answer. It is very Helpful to know now, that it is normal that the Array performs that bad. As it is no Option for me to buy a new Server for Homelab and put 10 Disks in it, i would rather suggest to go full SSD now here, since the Prices for SSDs are low as never before. I...
  8. ZFS bad Performance!

    Alright, yes, its just a Homelab with later about 30 TB Space and various "Gaming" Servers and RDP / Terminal, Nextcloud Servers.. With Hyper V and NTFS i could use Consumer grade SSDs...

  11. ZFS bad Performance!

    Hello, Here the Output: The Server is a Dell R710 with SAS Cables on the HBA. In my experience, a failure in that connection is resulting in very bad Performance, what i cant explain to myself with fio. Greetings

    The Disks are managed by ZFS, they are directly on a HBA. The Host is on the 500 GB SSD Mirror with Samsung SM883a SSDs. I just testet again, the IO delay peeks..
  14. ZFS bad Performance!

    Alright, sadly the Power was already set to maximum in the Dell, ive set it to OS control now. Im wondering, why the CPU Frequency was not always maximum as i testet it. Here the Output sir: vmstat: FIO...
